Before operating the RTK GPS, you should have the following:
ALTA X with RTK GPS
If you are retrofitting RTK GPS onto an existing ALTA X, follow the installation guide.
ALTA X running firmware v1.3 or above (see firmware update steps here)
Telemetry Radio, such as the Freefly FRX Pro
Base Station RTK GPS module on a stable mount (tripod is recommended!) and a USB-C Cable
ALTA QGroundControl v1.3 or above running on Windows or macOS (download on support page)
Get ALTA powered on and ready to fly
Install base station module onto mount
Connect ALTA QGroundControl to aircraft
Click the "RTK" symbol to open the status window
Connect base station module to laptop via USB
Ensure QGroundControl recognized the module
Open RTK status window and press "Restart" button to initiate survey-in.
Wait until GPS Status says "GPS Initializing."
Note: If the status does not change after 10 seconds, refer to troubleshooting section.
Wait for GPS Status to change to "Survey-in Complete".
Note: The survey-in process will complete after the minimum survey-in time has completed (typically 180s) AND the accuracy is below the configured threshold (2m). See the configuration page for adjusting these parameters.
Wait for Aircraft GPS status of "RTK GPS Lock (fixed)"
Ensure that Aircraft location is correctly indicated on the map
Fly and enjoy!
